She's punished with library duty which coincidentally (rather than through skill) leads to her uncovering someone in disguise, but too late to prevent the person they're working with from achieving their goal. There are examples in TCW of her "saving the day" to one extent or another but I don't think this is one of them.

I haven't seen the episode for a while, but I think we can call defeating and capturing the bad guy saving the day. Not that she was the only hero, but if Cato wasn't captured, she wouldn't have squealed and given them the info in the end, so it was pretty crucial.

Lightsaber Lost. Unless one were to count her finally finding her own lightsaber with help from a Jedi Master as somehow saving the day...

Lightsaber Lost was a good example of how to use Ahsoka properly. As a Padawan, she was a good combination of fallible, but determined, and ultimately capable. She didn't outshine the episode's Master, and instead was shown to be actually learning from him, with those lessons contributing to her success rather than simply succeeding on her the merits of her usual "spunkiness". I feel similarly about Padawan Lost and Wookiee Hunt. Even the Slaver trilogy of Season 4.

I don't entirely disagree, but I've already stated why I disagree to some extent. I'm ready to agree to disagree to avoid running in circles if you are.

If (Simus,) Darth Maul and Darth Vader are any indication, she'd have enough Force abilities left to still make her a much greater threat than someone with zero Force abilities like Grievous.

So maybe rather than kill Grievous, she'd lock him up, kidnap the chancellor (which would explain how several jedi were defeated ) then disappear after battle over coruscant and the real Grievous faces Kenobi?

...Now that I think about it, there's probably a fanfiction that about that.
